How do I implement an option menu in my android application? I tried code from Android Developer but I get errors. Such as these: Element menu must be declared. Here is my code
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/new_game"
android:icon="@drawable/ic_new_game"
android:title="@string/new_game"
android:showAsAction="ifRoom"/>
<item android:id="@+id/help"
android:icon="@drawable/ic_help"
android:title="@string/help" />
</menu>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.lucavanraalte.test" >
<application
android:allowBackup="true"
android:icon="@mipmap/ic_launcher"
android:label="@string/app_name"
android:supportsRtl="true"
android:theme="@style/AppTheme" >
<activity android:name=".MainActivity" android:screenOrientation="portrait">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
</manifest>
In your java code, add this onCreateOptionsMenu
to show optionMenu,
@Override
public boolean onCreateOptionsMenu(Menu menu) {
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.option_menu, menu); //your file name
return super.onCreateOptionsMenu(menu);
}
Keep your under res\menu\option_menu folder,
<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/new_game"
android:icon="@drawable/ic_new_game"
android:title="@string/new_game"
android:showAsAction="ifRoom"/>
<item android:id="@+id/help"
android:icon="@drawable/ic_help"
android:title="@string/help" />
</menu>
Now, if you want to set onOptionsItemSelected
i.e onClick event for that ou can use,
@Override
public boolean onOptionsItemSelected(final MenuItem item) {
switch (item.getItemId()) {
case android.R.id.new_game:
//your code
// EX : call intent if you want to swich to other activity
return true;
case R.id.help:
//your code
return true;
default:
return super.onOptionsItemSelected(item);
}
}
